Problems solved by technology

[0002] At present, the construction method of the bow section of the ship is: the inner bottom is used as the base surface, and after the longitudinals of the outer bottom are positioned, the outer plate is reversed, and then turned over as a whole, and the internal structure is welded. This construction process requires a crane to cooperate with a hoisting horse. Segmental turning, although it avoids the overhead welding operation, it requires construction personnel to perform segmental turning, which increases the labor intensity of the construction workers, and welding after segmental turning is very easy to produce deformation, resulting in changes in the main dimensions of the segment, which cannot meet the requirements Accuracy tolerance requirements require rework, which greatly affects production efficiency

Abstract

The invention provides a normal construction method of a ship bow section outer plate. The normal construction method comprises the steps that S1, a side view and a cross section view of the bow section outer plate and a rib molded line on a main ship body are made; s2, obtaining a cross section drawing of the jig frame; s3, obtaining a cross section drawing of each rib jig frame template; s4, machining each rib jig frame template; s5, a jig frame field operation plane graph is obtained; s6, the stand column is machined; s7, processing an outer plate; s8, the machined rib jig frame formworks and the corresponding stand columns are subjected to small assembly installation, rib formwork frames are obtained, and all the obtained rib formwork frames are hoisted to the jig frame ground; s9, hoisting an outer plate; the jig frame formworks are built according to the curvature of each rib molded line on the outer plate, it is guaranteed that the working faces of the jig frame formworks are tightly attached to the outer surface of the outer plate, and the supporting stability during operation is guaranteed; in addition, a normal building mode is adopted, turning-over operation of a traditional reverse building mode is avoided, and the construction efficiency and the construction quality are improved.
